Quite correct mate.
In fact, all fittings and nuts on acetylene equipment is left hand thread and furthermore marked with a groove cut on nut/fitting for identification to prevent accidental connection to the oxygen side...

all fuels are l/h (have a notch at corner of nuts) oxy and innerts are r/h threads
regulators should always be marked for type of gas and never mixed as its very dangerous (like acetlyene over pressurised out of its acetone will explode its a very unstable gas and can burn on its own with no oxygen!)
saying that co2 and argon can be swaped but purge out co2 for when using pure argon
pub bottles have a diffrent fitting to industrial cyl


also oxy equipment should be kept totaly oil and ptfe free as can burn internaly thats verry unsafe!
